Im still sold on dust. A dust ring around the edge
of the solar system would have been undetectable
by the voyager series.

PLUS it would account for both probes slowing down......

But not with the same rate. *If* the two probes speeds are
different by 10%, and the density of dust is the same along the
two paths, and the dust velocity radially outwards is zero, then
the acceleration due to the impulse difference should be along
the lines of 19%. But it is not.

....
But we can say what its not.......

Its NOT a planet
Its NOT a star
Its NOT a moon
Its not ANY ONE object that can be in solar
orbit (.)
It CANNOT be an object in which the solar
system is bound.

Yes, it could be an orbitting halo of Dark Matter. But that
means that every planet starting with/after Jupiter would be
funkey.

If it is gravity, then the probe should have been
deflected off course, I have not seen any data
indicating this.

An anomalous sunward acceleration (ASA) *is* like gravity, and
the ASA *is* indicated by the data.

Not to mention that any one of the aformentioned
possiblites would have only effected ONE of the
probes (Although I think of the trojen asteriods
trapped by Jupiter and wonder, but then again
these objects are in orbit and not traveling in a
straight line)

What does that leave us that naturally occurs in space?

Dust
Gas
Solar Wind (or similarly classified phenominon)
cosmic rays?

A sunward-facing solar sail (aka. radio dish) with a hot
power-plant behind it providing net-sunward thrust. Present in
all craft. Intensity of the Solar output falls off by 1/r^2
(outward on the sail), and the radioactive source falls off
1/(e^kt) (reduces inward on the sail).

Im going to stick with dust ........

Contraindicated. Even if the dust were slightly outbound, the
differential impulse would be greater (and more would be required
to provide the acceleration detected). And if the dust were
inbound, the acceleration is then wrong and abother cause needs
to be sought.
